It’s not as though we Star Trek fans have any room to boast about “originality” that subsequent series/movies have strayed from. The Original Series was sold to Desilu as “A Wagon Train to the stars,” two of the principle actors (Nimoy & Kelley) had starred in Western films and TV series, and the production budget was so tight that they frequently had to reuse props and even entire sets from other productions (yes, even Westerns) to cut down on costs. And for that, you got a series that probably has a dozen episodes out of 79 that most people can remember, another dozen or two that you go “Oh yeah,” and the rest are of the “Oh yes, that one” variety.
